I’m not an avid soup eater, but I do cook primarily one-dish meals, so I do occasionally make a batch of soup – never broth, always a meal-in-a-soup.
I probably eat more hot-and-sour soup than any other kind. Whenever my wife or I have a cold, I make 3 quarts or so. I begin with chicken stock or broth, put whatever’s at hand in it, usually some or all of: tofu, shiitakes, scallions, onions, pork, chicken. Spiced with Thai or Hunan chiles, white pepper, and rice vinegar, thickened with corn starch, and with a little soy sauce. Served over noodles.
My favorite soup is probably black bean, served either with bread or over rice. My favorite bread is made with spent brewing grain. I usually do 2:1 white to either whole wheat or rye flour, 1.25 c each milk and water, some molasses or malt extract, and 2 c of grain husks. It’s always dense and moist.
My wife’s favorite soup is phoc (pronounced fuh, Vietnamese beef noodle soup). I keep beef bones in the freezer, and whenever we have 5 pounds or so, make a batch of broth, usually spiked with a few bouillon cubes. Get some sort of Oriental noodles (wheat, rice, or bean), put them in the bottom of a deep bowl, put some shaved rare or raw beef on them, and then pour broth over the whole thing. Serve with sliced chiles, limes, mint, cilantro, bean sprouts, or anything else that strikes your fancy.
Another bread I make occasionally is Russian pumpernickel. IIRC, it has coffee, onions, and vinegar in it. Best if you can find dary rye flour, which I haven’t seen in years. Very strongly flavored and rich. Kinda the stout of the bread family.
